Orbital characterization of GJ1108A system, and comparison of dynamical mass with model-derived mass for resolved binaries
T. Mizuki, M. Kuzuhara, K. Mede +55
We report an orbital characterization of GJ1108Aab that is a low-mass binary system in pre-main-sequence phase. Via the combination of astrometry using adaptive optics and radial v…
High-contrast Polarimetry Observation of T Tau Circumstellar Environment
Yi Yang, Satoshi Mayama, Saeko S. Hayashi +52
We conducted high-contrast polarimetry observations of T Tau in the H-band, using the HiCIAO instrument mounted on the Subaru Telescope, revealing structures as near as 0.$\arcsec$…
The Fundamental Stellar Parameters of FGK Stars in the SEEDS Survey
Evan A. Rich, John P. Wisniewski, Michael W. McElwain +59
Large exoplanet surveys have successfully detected thousands of exoplanets to-date. Utilizing these detections and non-detections to constrain our understanding of the formation an…
A Resolved Near-Infrared Image of The Inner Cavity in The GM Aur Transitional Disk
Daehyeon Oh, Jun Hashimoto, Joseph C. Carson +47
We present high-contrast H-band polarized intensity (PI) images of the transitional disk around the young solar-like star GM Aur. The near-infrared direct imaging of the disk was d…
SCExAO and GPI Band Photometry and Integral Field Spectroscopy of the Young Brown Dwarf Companion to HD 1160
Eugenio V. Garcia, Thayne Currie, Olivier Guyon +51
We present high signal-to-noise ratio, precise photometry and band (\gpiwave~m) spectroscopy of HD 1160 B, a young substellar companion discovered from the Gemini NICI…
Radial decoupling of small and large dust grains in the transitional disk RX J1615.3-3255
Robin Kooistra, Inga Kamp, Misato Fukagawa +56
We present H-band (1.6 μm) scattered light observations of the transitional disk RX J1615.3-3255, located in the ~1 Myr old Lupus association. From a polarized intensity image, tak…
SEEDS direct imaging of the RV-detected companion to V450 Andromedae, and characterization of the system
K. G. Hełminiak, M. Kuzuhara, K. Mede +49
We report the direct imaging detection of a low-mass companion to a young, moderately active star V450 And, that was previously identified with the radial velocity method. The comp…
Constraining the Movement of the Spiral Features and the Locations of Planetary Bodies within the AB Aur System
Jamie R. Lomax, John P. Wisniewski, Carol A. Grady +54
We present new analysis of multi-epoch, H-band, scattered light images of the AB Aur system. We used a Monte Carlo, radiative transfer code to simultaneously model the system's SED…
Extreme Asymmetry in the Disk of V1247 Ori
Yurina Ohta, Misato Fukagawa, Michael L. Sitko +60
We present the first near-infrared scattered-light detection of the transitional disk around V1247 Ori, which was obtained using high-resolution polarimetric differential imaging o…
Near-Infrared Polarimetry of the GG Tauri A Binary System
Yoichi Itoh, Yumiko Oasa, Tomoyuki Kudo +47
A high angular resolution near-infrared polarized-intensity image of the GG Tau A binary system was obtained with the Subaru Telescope. The image shows the circumbinary disk scatte…
Detailed structure of the outer disk around HD 169142 with polarized light in H-band
Munetake Momose, Ayaka Morita, Misato Fukagawa +59
Coronagraphic imagery of the circumstellar disk around HD 169142 in H-band polarized intensity (PI) with Subaru/HiCIAO is presented. The emission scattered by dust particles at the…
